SUCKER-ROD ELEvA'roa AND WRENCH.

Application filed August 11, 1922. Serial No. 581,220.

To all whom it may concern: I

Be it known that I, BASIL Rose, a citizen of the United States, and aresident of Louisa, in the county of Lawrence and State of Kentucky,have invented certain new and useful Improvements in Sucker-RodElevators and Wrenches, of which the followin is a specification.

My invention is a'sucker rod elevator and wrench, and it consists in thecombinations, constructions and arrangements herein described andclaimed.

An object of my invention is to provide a sucker rod elevator and wrenchwhich will afford facilities for adjusting and elevating sucker rods inwells expeditiously, conveniently and without possibility of a suckerrod engaged by the device becoming disconnected therefrom while beingelevated or adjusted A further object of my invention is to provide adevice of the character described which embodies means operatedautomatically upon the placing of the device in position to raise asucker rod to lock the device in engagement with the sucker rod.

A still further object of my invention is to provide a device of thecharacter described which is relatively simple in construction, notlikely to get out of order easily and thoroughly practically commercial.

()ther objects and advantages will be apparent from the followingdescription, and the novel features of the invention will beparticularly outlined in the appended claims.

My invention is illustrated in the accompanying drawings, forming a partof this application, in which;

Figure 8 is a relatively enlarged fragmentary sectional view, thesection being taken substantially along the line 8-8 of Figure 1, and IFigure 9 is a perspective view of a locking pin comprised in the device.

n carrying out my invention, I provide means adapted to releasablyengage and hold the noncircular relatively reduced portion of a suckerrod or the like so that the latter may be elevated in a well andadjusted or repaired. Such means include a rod engaging member 1 havingthe form best seen in Figure 3 and a carrying block or member 2 by meansof which the rod engaging member 1 is rotatably supported and with whichthe rod engaging member co-operates. The carrying block 2 preferablycomprises a pair of superposed similar sections 3 and 4 respectively,each of the sections having a central bore 5 merged adjacent to one endor face of the section into a counter-bore 6. A radial slot 7 extendsfrom one edge of each of the sections 3 and 4 through the walls of thebore 5 and the counter-bore 6, the slots 7 having straight substantiallyparallel side walls between which the non-circular portion of a suckerrod of ordinary construction may be moved. As stated, the sections 3 and4 are arranged in superposed relation so that when the bores 5 thereofare in axial alinement, the slots 7 thereof are in register and thecounter-bores 6 are also in register and in open communication with eachother. Dowel pins 8 or like fastening means are employed to secure thesections 3 and 4 of the carrying block or member together in superposedrelation as shown.

The rod engaging member 1 comprises a substantially cylindrical body 9adapted to be received in the compartment provided by the counter-bores6 of the connected together sections 3 and 4 and to rotate in suchcompartment. The body 9 has relatively reduced axially alignedsubstantially cylindrical portions 10 extending from the opposite endsthereof in concentric relation to the body 9 and being adapted to extendthrough and rotate in the bores'5 of the sections of the carryin block.A slot 11 extends radially into tie body 9 and into the aligned reducedportions 10 of the rodengaging member. The slot-ll has straight sideWalls spaced apart to register with the OOIIGSPOIlCllIlg side walls ofthe slots 7 when the rod engaging member 1 is rotated to a certainposition in respect to the carrying block 2. It of course will beunderstood that the sections 3 and 4 of the carrying block are notassembled and secured together until the rod engaging member 1 has beeninterposed therebetween and positioned in respect thereto as described.

The body 9 of the rod engagingmember has an arcuate portion of itsperipheral wall cut away at 12 to provide a clearance space for a stopmember 13 which extends into the compartment provided by thecounter-bores 6 from a pocket defined by a complemental dove tailmortise 14 in the walls of the counter-bores 6. Spaced radiallyextending shoulders 15 and 16 are defined at the ends of the arcuateclearance space provided between the adjacent walls'of the cut awayportion of the body 9 and the counter-bores 6. The rotation of the rodengaging member 1 within the compartment provided by the counter-boresis thus limited because'of the engagement of the stop 13 with theshoulders 15 and 16. When the rod engaging member 1 is in. the positionin which illustrated in Figures 1 and 4, the slot 11 is in register withthe slots 7 anda non-circular portion of sucker rod or like member maybe moved through the alignedslots into engagement with the end or bottomwall of the slot 11. The carrying block 2 may then be rotated about theaxis of the rod engaging member 1 until the latter is in'the position inrespect thereto illustrated in Figure 5. At this time, the slot 11 isout of register with the slots 7 and the non-circular portion of thesucker rod will be held against movement from the slot 11 into the slots7 .The carrying member 2 is fashioned to provide straight parallel edgeportions 17 and 18, respectively, which are also parallel with the wallsof the slots and are merged at their ends remote from the entrance tothe slot 7 one into the other by a curved or arcuate portion of thecarrying block. Laterally extending shoulders 19 are provided at theends of the straight parallel portlons 18 of the edge walls of thecarrying block for a purpose which .will be hereinafter set forth.

The carrying block 2 is provided with axially aligned trunnions 20 whichextend therefrom at points adjacent to the shoulders 19 and at rightangles to the parallel side walls of the slots 7. The trunnions 20 maybe partially formed on the sections 3 and 4 as shown and are journaledin openings 21 formed through parallel end portions of divergent arms 22comprised in a tion 23 of a handle which is generally at 24.

The handle 24 includes in addition to the parts described a shankportion 25 which is of non-circular cross sectional contour and tapersuniformly from its juncture with the yoke portion 23 to its end. Thehandle 24 preferably consists of two eomplemental longitudinal sections,each of which includes one of the half portions of the shank and beingsecured together by dowel pin 26, screws or like fastening means.

An elongated loop or ring 27 has an enlarged portion 28 at one endprovided with an opening 29 therethrough which is in axial alignmentwith the longitudinal axis of the loop or ring. A headed pin 30 has theshank thereof extended through the opening 29 into an axially alignedsocket 31 formed in the end of the shank portion 25. A washer 32 may beinterposed between the head of the pin 30 and the inner wall of theenlarged portion of the loop or ring. The pin 30 may be removably heldwith the end portion of the shank disposed in the socket 31 through theagency of one of the dowel pins or screws 26 which is arranged to extendtransversely through the end portion of the pin. The arrangement is suchthat the ring or loop 27 is swivelled on the shank of the handle.

esignated oke por- It is desirable that the rod engaging membox 1 shallbe releasably held in the position illustrated in Figure 5 when thehandle 24 is disposed at right angle to the position illustrated inFigure 1, or in other words in a position to elevate a sucker rodengaged by the member 1 in the manner described. To this end, myinvention provides a locking pin 33 having a shank portion adapted toslide in a radial bore 34 formedthrough the walls of the carrying block2 so that the inner end portion of the'shank which is rounded and whichis indicated at 35, will extend into the compartment provided by thecounter-bore 6 and into the slot 11 of the rod engaging member when thelatter is in the position shown in Figure 5 to prevent such rotation ofthe rod engaging member rounded end portion of the shank of the lockingpin being engaged by a side wall of the slot 11 and the locking pinmoved outward by a camming action until the rod engaging member 1 isfree to be rotated to the position illustrated in Flgures 1 and 4:.Obviously, spring means not shown may be provided between the head 36ofthe locking pin and the shoulder 38 to urge the locking pin outward.\Vhen the handle 24 is in a position at right angles to that illustratedin Figure 1, the outer end of the enlarged portion of the bore 34 willbe obstructed by a portion of the adjacent wall of one of the arms 22 sothat the locking pin will be held against movement from lookingposition. However, when the handle 24 is in the position illustrated inFigure 1 in respect to the carrying block 2, the locking pin 83 may moveoutward since the head portion thereof may enter a recess or cavity 39which is formed in the inner wall of the adjacent arm 22 in position tothen register with the enlarged portion of the bore 37 and to be out ofregistration with the latter when the handle 24 is swung from theposition illustrated in Figure 1 to lifting position disposed at rightangles thereto.

From the foregoing description of the various parts of the device, theoperation thereof will be readily understood. The device can beinstantly adjusted in engagement with the non-circular portion of asucker rod of ordinary construction when the handle is in the positionin respect to the carrying block 2 illustrated in Figure 1. The carryingblock 2 is then rotated about the rod engaging member 1 until in theposition in respect thereto illustrated in F igure 5. The handle '24 isthen swung upwardly against the radial projections 19, at which time thehead of the locking pin will have been engaged by the inner side of theadjacent arm 22 of the handle and forced inwardly so that the lockingpin will be in looking position as shown in Figure 5. The engagedportion of the sucker rod will then be held against accidentaldisplacement and may be rotated or elevated in order that adjustmentthereof or repairs thereto may be effected.

Obviously, my invention is susceptible of embodiment in forms other thanthat illustrated in the accompanying drawings and I therefore consideras my own, all modifications and adaptations thereof which fairly fallwithin the scope of the appended claims.
